OIL BURNER Filed Sept. l, 1931 2 Sheets-Sheet 2 INVENTOR m o ATTORNEY Patented Nov.` 8, 1932 I PATENT OFFICE JOSEPH E. FOWLER, F `W0BJIE'S'JPER, MASSACHUSETTS on. BURNER Application iled September 1, 1931. Serial No. 560,607.

This invention relates to oil burners especially adapted for ranges, furnaces and boilers and has for the primary object, the provision of a device which will be safe or free from explosions and which is so constructed that the accumulation of carbon and the burning out .of parts will be reduced to a minimum.

Another object of this invention is the provision of a plurality of combustion and air chambers formed by nested cylinders so constructed and arranged relative to each other and to a fuel ring or base that a clean, clear blue flame Will be produced and capable of producing a maximum amount of heat from a minimum amount of fuel and said cylinders are capable of being removed or replaced on the base as a single unit and still permit separation of the cylinders when desired anddue to the various cylinders being movable ina single unit and separable from the base, permits the device to be more readily assembled in a furnace or boiler and to be cleaned or repaired, when desired.

A further object of this invention is the provision of a removable deflector capable of being-folded to facilitate the handling and the assemblage thereof on a burner withina furnace or boiler.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a vertical sectional view illustrating an oil burner constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 1.

Referring in detail to the drawings, the numeral 1 indicates a burner support which includes a vertical standard 2 threaded into a hub 3 having radially extending legs 4 to which are adjustably secured bolts 5 forming feet for said legs and adapted to permit the device to be easily'leveled. The upper end of the standard 2 is threaded into a hub 6 provided with radially extending arms 7 supporting a base 8 of annular formation. The base^8 is provided centrally thereof with an air opening 9 surrounded by an annular 55 flange 10. A plurality of relatively spaced annular flanges are formed on the base 8 upwardly of the flange 10fand are indicated by the reference characters 11, 12 and 13. The i' flanges are 'provided with bevelled seats 14. 6o The flanges 11 and 12 form therebetween an annular fuel chamber 15 While the flanges 10 and 12 form therebetween anannular fuel VAchamber 1.6.A The fuel chambers 15 and` 16 are fed by fuel from feed ipes 17 threaded 65 in openings formed in the ase 8 and it is to be understood that the feed pipes 17 receive fuel from a suitable supply having regulating means for controlling the fuel to the chambers in desired amounts. An annular rest l8is formed between the flanges 12 and 13 and a similar rest 19 is provided adjacent the periphery of the base and outwardly of the flange 11.

Annular wicks 20 are mounted in the fuel 75 chambers 15 and 16 and are preferably constructed of asbestos and are surrounded by metallic bands 21 provided with crimped portions or projections 22 adapted to abut the outer side walls of the fuel chambers for positioning the wicks away from the flanges 11 and 13 and at a proper location within the fuel chambers. By referring to Figure l it will be noted that the height of the wicks is greater than the heights of the flanges 11 and 85 13 so that the vapor -of the fuel therefrom may readily enter combustion chambers 23 and 2l and which ywill be hereinafter more fully described.

The base and pedestal may be constructed from a cast metal thereby reducing the cost of manufacture.

A burner 25 is mounted upon the base and comprises a plurality of nested cylinders ,preferably constructed from steel or similar material andthe various cylinders are indicated by the reference characters 26, 27, 28, 29 and 30. By referring to Figure 1 it will be seen that the cylinders 27 and 28 are arranged in close relation and also the cylinders 29 100 and for the purpose of forming the combustion chambers 23 and 24 disposed over the Wicks 20. The space between the cylinders 28 and 29 is of considerable area to form an air chamber 31. The cylinder 30 within itself forms an `air chamber 32 disposed directly over the air openingf9 of the base. The cylinders 27, 28, 29 and 30 are provided with a suitable number of perforations for the purpose of admitting air to the combustion chambers from the air chambers in order to produce a dame within the combustion chambers which will provide maximum heat with a minimum consumption of fuel. The cylinder 26 is unperforated and has its lower edge spaced from the base and has formed integral with its upper edge anl annular flange or ring '33 adapted to engage over or rest on lugs 34 formed on the outer face of the cylinder 27. The upper edge of the cylinder 27 is bent angularly to form a lip or rim 35 overlying the upper end of the combustion chamber 23 and is adapted to direct the heat and flames escaping from the combustion chamber 23 inwardlyof the burner and also the lip 35 overlies lugs 36 carried by the outer, face of the cylinder 28. The cylinder 29 is also provided with a lip 37 at its upper edge overlying the combustion chamber 24 andits function is similar to the lip 35 and overlies lugs 38 carried by the outer face of the cylinder 30.l 'An annular perforated plate 39 is welded or otherwise secured to the inner face of the cylinder 28 downvardly of its upper edge and abuts the outer i. face of the cylinder 29. and is adapted to admit air to the air chamber 31. Lugs 40 are carried by the outer face of the cylinder 29 with the perforated plate 39 overlying the same. A perforated plate or disk 41 is welded or otherwise secured to the inner face ofthe cylinder 30 downwardly from the upper edge thereof and is adapted to admit air to the chamber 32. A suitable handle 42 is fixed to the disk or plate 41 whereby all of the v cylinders may be lifted from the base as a single unit and due to the arrangement of the edge of the cylinder' 27 onto the seat 19 when the burner is applied to the base.

The cylinder 29 engages the rest 18 and against the flange 13, the bevelled faceof the latter facilitating in-guiding the lower edge of the cylinder 29 onto the rest 18. The cylinders 28 .and 30 are of a shorter length than the cylinders 27 and 29 and have welded or othervwise secured to their lower ends substantially conical shaped elements` 43 adapted to rest upon the bevelled faces ofthe flanges 10 and 12 and are constructed of a solid material such as steel or the like and are adapted to deflect the vapor from the fuel laterally and upvadly into the combustion chambers 23 an 2 From the foregoing description taken in .m connection with the accompanying drawings, it will be noted that the fuel vaporized in the oil trough or oil ring burns within the combustion chambers and the latter are supplied with asuitable or -desired amount of air fromthe air chambers in order to provide a flame having an excessive amount of heat. A device constructed in accordance with the foregoing provides combustion chambers one 30 within the other and by increasing the number of cylinders and the seats therefor and fuel supplying means on the base, any desired number of combustion chambers may be had within a single burner.

, A deliector 44 comprises a circular shaped plate constructed from semicircular shaped sections secured together by a hinge 45 whereby the sections may be folded one upon the other to reduce the size of the deflector when ge desired' and when assembling the device within-a furnace or boiler and which will be hereinafter more fully described. Substantially triangular shaped legs 46 are secured to the deflector 44 and rest upon the perforated disk 9c 41 when the deflector is positioned upon the burner, and the flames and heat from. the combustion chambers will be caused to travel laterally of the burner. A ring 47 is carried by the delector whereby the same may be 10o easily lifted and handled when desired.

A burner constructed in accordance with the foregoing may be easily and quickly assembled within a furnace or boiler and be of such' a size when assembled that it cannot -i05 be placed in the furnace or boiler in assembled posit-ion and due to the cylinders being removable from the base in a single unit, they can be easily passed'into the furnace by a receiving door and then the base and pedestal '11o placed in the furnace or boiler and assembled and then the cylinders as of a single unit positioned upon the base.

It will be further noted by` referring to Figure 1 that no small grooves or fuel con-f 115 duits are in the burner consequently the possibility of the burner becoming clogged by the accumulation of carbon is reduced to ta .minimum and also any carbon which may Having thus described my invention, what I claim is:

An oil burner comprising'a fuel receiving base, means supplying the base with fuel, a plurality of nested cylinders forming combustion and air chambers mounted on the base and certain of said cylinders having perforations, perforated elements closing the air chambers at their upper ends, angularly disposed lips formed on certain of said cylinders and overlying the upper ends of the combustion chambers, and lugs carriedby said cylinders and engaging the lips and perforated elements for permitting sald cylinders to be removed from the base in a single unit and to perilit sepa-ration of the cylinders when des1re In testimony whereof I aix my signature.
